A
administration
network
The private network within the HP XC system that is used for administrative operations.
B
base image The collection of files and directories that represents the common files and configuration data
that are applied to all nodes in an HP XC system.
branch switch A component of the administration network. A switch that is uplinked to the root switch and
receives physical connections from multiple nodes.
C
cluster A set of independent computers combined into a unified system through system software and
networking technologies.
compute node A node that is assigned only with the compute role and no other. Jobs are distributed to and
run on nodes with the compute role; no other services run on a compute node.
.
D
DHCP Dynamic Host Control Protocol. A protocol that dynamically allocates IP addresses to computers
on a local area network.

Control Protocol
See DHCP.
E
enclosure The hardware and software infrastructure that houses HP BladeSystem servers.
G
golden image A collection of files, created from the golden client file system that are distributed to one or
more client systems. Specific files on the golden client may be excluded from the golden image
if they are not appropriate for replication.
H
head node The single node that is the basis for software installation, system configuration, and
administrative functions in an HP XC system. There may be another node that can provide a
failover function for the head node, but HP XC system has only one head node at any one time.
host name The name given to a computer. Lowercase and uppercase letters (a–z and A–Z), numbers (0–9),
periods, and dashes are permitted in host names. Valid host names contain from 2 to 63
characters, with the first character being a letter.
I
I/O node A node that has more storage available than the majority of server nodes in an HP XC system.
This storage is frequently externally connected storage, for example, SAN attached storage.
When configured properly, an I/O server node makes the additional storage available as global
storage within the HP XC system.
iLO Integrated Lights Out. A self-contained hardware technology available on CP3000 and CP4000
cluster platform hardware models that enables remote management of any node within a
system.
